Question 1209231
<br>
(1) Treat each husband-wife pair as a single unit.  You then have four things to arrange around the table.<br>
(2) If they were being arranged in a line, the number of ways of arranging them would be 4*3*2*1 = 4! = 24.  But since they are being arranged around a table, there are four possible "starting points" for the arrangement, so the number of ways to arrange the four groups around a table is 24/4 = 6.  (In general, there are (n!) ways of arranging n things in a line and ((n-1)!) ways of arranging n items in a circular pattern.)<br>
(3) Within each of the four groups, the man and woman can be in either of two orders.<br>
ANSWER: (6)(2)(2)(2)(2) = 96<br>
